Note that the PCIe spec mandates MSIs while old style interrults (LSIs) are optional... The result is that there are already platforms (though not x86 just yet) being design with simply no support for LSIs on PCIe and I've heard of devices doing that too (yeah, that's weird, they wouldn't work in windows I suppose). I suppose none of this affects x86 for now... For ppc, once we get our new MSI layer in, however, I'll have to keep them enabled by default, though there are fewer platforms involved and the chances at this point are fairly high that they all use a working chipset.
